Why is there no sound out of the left side of my Pioneer receiver? It's an old receiver (70's) and is very heavy.?


Can I buy a new tube at the store and is it a push in style tube? Or would it need to be heated up and stuck on ?

I really like it and would like it to work properly 

Update 2:

Only the right side works (either speaker will make sound).

The left side makes no sound wispeaker speaker.

Update 3:

left side makes no sound from left back or left aux.

The receiver was capable of making sounds from 4 speakers total.

    For those who have no clue: 

    NO 1970s receiver has tubes. 


    Take it to an audio repair shop.

    OK, let's use the process of elimination:

    The first thing to check is the wiring.  Old wires get fragile with age and break inside.

    Move the non-working speaker over to the working one.  Switch wires to make sure to make sure it's not the wire.  If it works the problem is not the speaker.

    Now move the working speaker over to the non-working side and connect it.  If it works then the problem is not the wire.  If it doesn't work then check it again with the working wire.  If that doesn't work then the problem is the receiver.
